Yes, exactly. I turned left after walking from the Z wing that is restricted to US-bound flights, following the signs, and came across a temporary sign post in the middle of the concourse. Where before you would keep going, out of security along with foot traffic bound for baggage claim, and then circle back around to the Z Skyline station for a transfer to B non-airside, instead I found this temporary sign across from Z11. Turn left to go to Schengen passport (and A), turn right to go down the stairs to the tarmac and a bus transfer to a bus gate in B.

It all felt very temporary? Perhaps a test? It was so much dramatically faster a transfer. ^
